Analytical models for the thermoacoustic performance of fibrous materials

This work investigates analytical models for the thermo-acoustic performance of fibrous materials. Through well-established analytical models, porosity 𝜙 was identified as a main parameter connecting both Johnson-Champoux-Allard semi-phenomenolog￾ical acoustic formulations and effective thermal conductivity modelling. The initial discussion herein proposed is seeking an ap￾proach to balance the weight between thermal and acoustic protection in sustainable fibrous insulating systems. The models are validated using Posidonia Oceanica fibers experimental measurements.
